Parameters for Tungsten and Fluorescent Light Detection
The parameter TL (tungsten light) is used to define the threshold value for the
artificial light detection. CTL is used to correct the colors of those frames whose
colors are above the threshold value. The strong yellow-reddish color cast is
neutralized and the prints take on a character resembling daylight.
Artificial light shots are subjects taken in a warm light (incandescent lamp, candle
light).
